So this evening while trying to d/l and install MyWi I somehow hosed my JB 3.1.2 iPhone. It will not even boot up so I know I need to restore it via DFU mode. My question is, anyway to keep from losing 3.1.2 in the process?

Download the correct 3.1.2 firmware from here if you haven't already.
Go into iTunes and on the summary page, hold the shift button and click restore at the same time, and then load the proper firmware.
The rest is the same from there.

That would work for a 2G and a 3G iphone but for the 3GS it gets more complicated when SHSH's come into play....

Thanks Nick. I get off in about 30 minutes and hope to try it when I get home. But to clarify one thing. You state "hold the shift button". Is that with a Windows, Mac or both? I have a Mac so I just wanna make it's the same key either way.

Question re this site. If one has upgraded to 3.1.3 from a JB phone can they restore to 3.1.2 with the proper firmware?

I have a couple of friends that have accidentally upgraded their JB phones to 3.1.3.
